Not trying to start any bashing, but not caring about things that you feel don't apply isn't the greatest attitude to have.
Say something comes along in your career in aviation that you don't like and you decide to half ass your way through it, and your employer notices and doen't care for it. I am not saying you will do it, but the way you tend to do things can carryover. I have taken plenty of courses I don't care for, but I tried to get at least a B if not an A in them. It is a challenge I set for myself and has given me 3.7. Trust me, it will you feel good after you have done it.
